Fig.131 is a three-piece heavy duty ball valve designed for reliable performance in demanding industrial applications.
The robust three-piece construction allows the end caps to be welded directly to the pipeline without removing the valve body, ensuring efficient installation while protecting internal sealing components.
With its durable design, wide connection options, and ISO 5211 direct mounting flange, Fig.131 is an ideal solution for applications requiring strength, hygienic service, flexibility, regulating capability, and ease of automation.
Customized V-port ball designs are available on request for regulating service.
1. Groove on the stem show the direction of ball.
2. Stem is square which is good for automation, having four driving points to absorb strength.
3. Top flange according to ISO5211, together with square stem, makes it suitable for direct mounting of actuators, without using bracket or coupling.
4. Lock cap for nut, ensure life loaded sealing.
5. Fully encapsulated body sealing provide safe sealing and directly welding in line without disassembly.
6. Anti-static device for ball-stem-body.
7. Precisely machined and mirror polished ball surface for bubble tight shutoff with low operating torque.
8. Relief hole in stem slot of ball to balance the pressure in the body cavity.
9. CF8M ball valves with welding ends CF3M material as standard, which reduces inter-granular corrosion by welding.
